A labile product in the photoreduction of tetrakis-(1,10-phenanthroline)diaquo-µ-oxo-di-iron(III)
Abstract
Photoreduction of tetrakis-(1,10-phenanthroline)-diaquo-µ-oxo-di-iron(III) in aqueous medium to form [Fe(phen)3]2+(phen = 1,10-phenanthroline) seems to continue even after cessation of irradiation; kinetic evidence supports the formulation of a thermally labile peroxo-bridged binuclear complex, which undergoes thermal reduction and rearrangement to [FeII(phen)3]2+.
